First of all, we should understand the structure of 6* 19+FC, with 6 strands per strand 19 steel wire.

6* 19 The common wiring standard is the diameter ÷ 15.5, and the result is ≈ 1.2, which is the diameter of the outer wire.

According to the regulations, the center line is 1. 1 times the diameter of the outer line, which is ≈ 1.3.

It is stipulated in the inspection items and judgment standards of wire rope production license that if the central steel wire is not thickened, the quality scoring standard of wire rope products will be affected.

With the diameter of steel wire, our calculation is much simpler.

First, calculate the outer yarn 1.2, with a diameter of 1.2 and an area of 0.6*0.6*3. 14, which is approximately equal to1.

Multiply by 18 (excluding the central filament, each strand has 18 outer filaments).

Multiplied by 6(6 strands), it is approximately equal to 122mm2.

Then add the total area of the six center lines ≈7.96, and the result is129.95mm2.

Wire ropes of other structures can also be calculated by this method.
